<font size=2 face="sans-serif">Hi list,</font>
<br>
<br><font size=2 face="sans-serif">We've been able to partly decipher the
Ventana BIF format, however we have a problem figuring out the final tile
stitching data. We'd be quite willing to contribute our code to OpenSlide,
if somebody would be able to continue working on it and figure out the
stitching. We have some technical understanding on what kind of information
is contained in the BIF-files as well, for those interested.</font>

<br><tt><font size=2>Hi all,<br>
<br>
I've pushed to master a significant set of cleanups:<br>
<br>
- The ops midlayer has been removed. Vendor backends are now responsible
<br>
for both slide parsing and tile rendering. The reusable parts of
the <br>
ops midlayer have been converted into generic utilities, and the <br>
format-specific pieces have been moved into the corresponding vendor <br>
backends.<br>
<br>
- The library now retrieves level dimensions, downsample factor, and <br>
tile size hints from a generic level struct which is instantiated and <br>
populated by the vendor backend.<br>
<br>
- GError is now used for all internal error reporting.<br>
<br>
These changes should make the OpenSlide codebase much easier to <br>
understand and modify.<br>
<br>
The introductory wiki page has been updated:<br>
